JTAG programming issue for Cyclone 4 chip

I use the chip EP4CE55F23. When I press Auto Detect, it detects the chip.

But when I try to program the SOF file, it shows the following message, (Quartus 13.1)

Error (209015): Can't configure device. Expected JTAG ID code 0x020F50DD for device 1, but found JTAG ID code 0x0FFFFFFF.

I use a buffer chip for the JTAG pins, like the following schematic

The programming pin header, J5 is a custom one and was tested before in other boards (but without the buffer chip)

    It seems that you are trying to configure a Cyclone IV FPGA, but you choose the Cyclone III one. When the selection page due to JTAG ID is shown, select the EP4CE55 option.

    No

    I selected the cyclone 4 chip. The picture I attached is just to show you that the programmer detects the chip successfully.

    After I removed the buffer chip, the programming worked. I think there is an issue in using that buffer chip or the schematic should be modified.
